Japanese researchers have developed a mouse that allows disabled users to operate their PC with nothing more than their breath.

The system features a tube placed in the user's mouth. A sensor within the tube measure the strength and duration of the user?s breaths, which are then converted into input commands. By combining strong and soft inhalations and exhalations, the user can move the cursor up, down, left, or right. Quickly and forcefully blowing or sucking air will produce right and left clicks, respectively.

The team at Kinki University?s Biology-Oriented Science and Technology Department's Human Ergonomic Engineering Robotics Research Lab developed the breath-operated mouse for the severely disabled who lack either the upper body mobility or appendages necessary to use a traditional mouse.
